  • Patent number: 9172718
    Abstract: A endpoint load rebalancing controller, method of controlling endpoint activity to suppress side channel variation and computer program product for controlling endpoint activity for suppressing side channel variation in information from utility company users, e.g., from power company endpoints. The load rebalancing controller monitors period to period endpoint service usage and predicts next period endpoint service usage. Whenever the controller maintains determines that the endpoint usage will exhibit a change that may be sufficient to convey activity information in side channel activity, the controller rebalances activity for the next period. Rebalancing may include shifting off-line execution from one period to another and capping or increasing on-line execution activity.

  • Publication number: 20150089638
    Abstract: A system, method and computer program product for protecting utility usage information from utility company users, e.g., power company endpoints. Smart meters monitor endpoint service usage to identify the start of a critical usage period. During critical usage periods the smart meters select and modulates a generic usage pattern by the difference between the pattern and actual usage. Instead of sending actual usage data, the smart meter sends the modulated generic usage pattern to the service provider. The service provider extracts the deltas and determines endpoint service usage from the extracted deltas.
